It has been found that the spectral energy density and radiation pressure of a Kerr nonlinear blackbody are larger than those of a normal blackbody, and there is a regular variety of the spectral energy density and radiation pressure in a Kerr nonlinear blackbody with the change of temperature and frequency.

通过和普通黑体比较发现，克尔非线性黑体的光谱能量密度和辐射压强都要比普通黑体大，非线性黑体中的热辐射光谱能量密度和辐射压强随着温度和频率的改变有着规律的变化。

The concept of grid relative density and boundary point extraction technique are proposed.Based on that,a clustering algorithm based on GRD for multi-density data sets is developed.

提出网格相对密度的概念和边界点提取技术，在此基础上给出了一种多密度聚类算法。

Relative density is defined as the ratio of the mass density of a substance to that of water under the same conditions of temperature and pressure.

相对密度系指在相同的温度、压力条件下，某物质的密度与水的密度之比。

Part 3 : determination of water absorption, apparent porosity, apparent relative density and bulk density.

NBR/modified montmorillonite and NR/HMMT nanocomposites were prepared by the mixing intercalation method with the monomers resorcin and hexamethylenetetramine complex . XRD and TEM showed that the interlayer spacing of HMMT had got much larger with RH addition and the layers of HMMT had dispersed in rubber matrix on nanometers. FTIR and crosslinking density results explained that chemical reaction had occurred between RH and rubber in the course of vulcanization, which improved the crosslinking density of rubber and enhanced the interaction between the rubber and HMMT.

采用单体混炼插层法，引入间苯二酚-六次甲基四胺的络合物，制备了橡胶／改性蒙脱土插层纳米复合材料。X-射线衍射分析表明：RH的加入使蒙脱土层间距不断扩大；TEM观察到无机片层在橡胶基体中纳米级分散；FTIR和交联密度的分析发现，在硫化过程中RH与橡胶发生化学键合反应，同时与改性蒙脱土相互作用，使得体系交联密度提高。

The experiment that is just enunciation, the royal crown eject of water quantity ratio gold bullion many, elucidation royal crown of density ratio gold bullion of the density be small, this certificate the royal crown don't use pure gold manufacturing.
